Crowd control in League of Legends: All types and effects

In League of Legends, hundreds of abilities can affect other units with crowd control effects, also known as CC. Crowd control effects will reduce the amount of control that the targeted unit will have on its ability to move, attack, cast spells, or reduce items, to varying degrees.

All types of crowd control effects in League of Legends

Here’s a table of all crowd control effects in League, including their name, description, and whether they fall under the major crowd control categories. Those categories are:

Total CC: Crowd control effect removes total control of the champion.
Disrupting: Crowd control effect disrupts a channeled or charged ability.
Immobilizing: Crowd control effect prevents the ability to control movement. Doesn’t mean that unit cannot move, only that the unit cannot control movement.
Disarming: Crowd control effect disables basic attacks.
